以编程方式获取给定的进程名称和ppid

Question

On Linux and other POSIX (?) operating systems - how to get name and parent pid of given (by pid) process? 在Linux和其他POSIX（？）操作系统上-如何获取给定（通过pid）进程的名称和父pid？ Currently I'm reading /proc but OSX doesn't have it. 目前，我正在读取/ proc，但OSX没有它。 On OSX I'm using libproc but that doesn't work on Linux: 在OSX上，我使用libproc，但在Linux上不起作用：

int ret = proc_pidpath (pid, pathbuf, sizeof(pathbuf));
if ( ret <= 0 ) {
    _dbg("   %s\n", strerror(errno));
    return false;
}

Unfortunately, when it comes to process info, every OS does things differently. 不幸的是，在处理信息时，每个操作系统的处理方式都不同。 If you only need to know about user-launched apps, look into the NSWorkspace class's runningApplicationWithProcessIdentifier: method. 如果只需要了解用户启动的应用程序，请查看NSWorkspace类的runningApplicationWithProcessIdentifier：方法。 Otherwise, you'll have to use a platform-specific sysctl as described here: 否则，您将必须使用特定于平台的sysctl，如下所述：
